Cream cheese and butter slightly. Add in sugar and continue to beat till creamy and fluffy.

Mix in the whole egg and egg yolk. Add the lemon and orange rind. Add milk gradually and fold in the flour to mix well. Fold in meringue gently but thoroughly. (to make meringue simply beat egg white and sugar to a stiff peak using an electric mixer on high.)

Pour batter into a greased cake pan. Bake baine marie style in an oven preheated to 170 ºC for 50 to 60 minutes or until golden brown and cake is set. Remove cake pan from the water bath and allow to cool completely in the pan on a rack.
